METAL IBEAD FOR PLASTERINGS.

Specification of Letters Patent. Application filed larch 11, 1912. Serial No. 682,960.

Patented Sept. 22, 1914.

To all whom it may concern."

Be it known that I, WILLIAM V. HEINZ, of La Salle, in the county of'La Salle and State of Illinois, have-invented certain new and useful Improvements in Metal Beads for Plasterings, of which the following is a specification.

My invention relates to sheet metal beads such as are applied usually for protecting the salient corners of the plaster walls; and the chief object of my improvements is to provide a sheet metal head which can be applied not only for protection to corners of different angles but also to level surfaces to serve as a line of division between different kinds of plaster laid on such surfaces. I attain this object by the means illustrated in the accompanying drawings, in which- Figure 1 is an elevation showing my improved bead as applied to a square corner, the'lower portion of which is of brick and the upper part frame, without the plaster.

ig. 2 is a cross section cut squarely across the bead as arranged for a square corner, the dotted lines showing the extreme position to which the side parts may be turned apart in order to fit a straight or level surface instead of a corner. Fig. 3 is a similar view to Fig. 2 but shows a modification of the front part designed for two-coat work, the side parts being turned apart to fit a corner having an obtuse angle, and the dotted lines indicating the depth of the ground and finishing coats of plaster, as applied thereto. Fig. 4 is a detail showing a perspective view of the front part detached from the side parts. Fig. 5 is a detail showing, in perspective, the modified form of the front part, detached. Fig. 6 is a horizontal section showing some additional bends in the side pieces.

Similar letters refer to similar parts throughout the several views.

y improved bead comprises duplicate sheet-metal side by A A and designed to be secured together and to the wall and to be embedded or cov-' ered with the coat of plaster, and an exposed outer part, or nose-piece B (the bead proper) to be attached to the embedded parts; so as to hold them together and stand and shelf incheswide and of any desired out exposed to view at the corner or surface of the plaster. The partsA A are formed, each, of a straight strip of galvanized iron about one parts designated generally length with a longitudinal bend at a near one edge leaving a marginal flange a of about one eighth inch extended preferably at right angles and running the entire length of the strip. At about a half inch from the bend a and parallel therewith is another bend 0 degrees, and leaving the remainder of the strip A flat. This fiat part is designed to fit against the wall and is provided with nail holes or slots a preferably extended diagonally of the strip so as to cross the mortar joints of brick walls, and facilitate the nailing into them for securing the parts A A to thewall.

That part of the strips which is between the bends a and a is designed to form the support proper for the bead B and is provided with a series of slots a each of which extends from one of said bends to the other and through which rivets or screw bolts C may be applied for holding the parts A A together when on a corner of the wall. Light wire strung through these openin obviously might be used instead of the bolts to tie said parts together, or solder might be used. It is noted that when the parts between the bends a a are brought together in parallel relation the remaining wider 'parts of A A having the nail holes, are extended at right angles as seen in Fig. 2 (full lines), and the tie bolts C are locand and tightened at the end of the slots a adjacent to the bend a WVhen a greater angle is desired the bolts are loosened as seen in Fig. 3. Said bolts are movable along the slots a so that when a further increase of the corner angle is desired it may be secured by moving the tie bolts in said slots toward thetbend a and tightening or loosening them so as to keep'the duplicate parts in contact at the bends a as seen in dotted lines Fig. 2.

Plaster openings a are made at frequent intervals through which the plastic mortar passes so as to fill the open space between the parts down to the bends ar which, when hardened, will keep the tie bolts firmly in place.

In Fig. 6 the being slightly corrugated at a, a, the object being to increase the rigidity to the strips; also to permit the plaster to take hold under the Hat pieces which will produce additional anchorage for the plaster.

The exposed bead B ma be of superior material. It is formed 0 a narrow strip side strips are shown as at a preferred angle of about 45- I made. I do not wish to be understood as limitinglm self to the rivets or screw bolts C for ing these parts together as the fastening may obviously be varied in many well known ways without departing from my invention. The cross-sectional interior shape of said part B is such as to slide over the marginal flanges a and engage below the same in order to hold said part B in place on its support, and also to permit the flanges a to rotate in the interior of part B, opposite the slot b, in compensation for the spreadin of the parts A from the angles shown in ful lines to the angles shown in dotted lines, Fig. 2.

When the parts A A are used on a frame structure of wood they may be sufliciently secured by means of nails driven into the frame through the slots a, or ordinary holes, but w en they are. used on a brick wall the nails must be driven into the mortar joints 0 and in order to hit such joints readily the slots a are extended diagonally and lap by each other so as to form practicall a continuous nail hole throughout the lengt of the head which shall cross the mortor joints at a suflicient number of points toafi'ord a secure fastening.

It often happens in fastenin the arts to a cornerof brick by nailing t roug the diagonal slots said slot will cross the mortar joints too near the corner to'afiord a ood holding. In such case I use clips .D %Fig. 1) whlchare each formed of a stri ofgalvanized sheet iron provided with 11 holes 0 and having their opposite ends folded on diagonal ines d, corresponding with the incline of the slots a, so that the fold d may be booked through said diagonal slots a. and ad'usted therein 60 as to.

bring some one of t with a mortar joint 0. provided at both ends of e nail holes a in line The folds d are the clips so that any cli is thereb made applicable on either si so the bric wall corner wherever a defective nailing place may occur.

When the parts are assembled and mounted on a corner, as shown in F' 1, the bead B is adapted to stand firmly in place and serve as a guide to the worlnnan when spreading the mortar, enabling-him to lay a straight even coat at both sides of the corner, first 'on one side and then on the other, without waitin for the first side to dry. The coat shoul lie parallel with the opposite sides'of the corner and have suflicient thickness to cover the parts between the bends a and a as indicated by the dotted lines Fig. 1, which show the location of the' lines of the outer surface of the plaster coat ,with flanges diverging to the wall for attaching at op fills t e entire space under the bead B and joins the bead without forming a featheredge so thin as to be liable to break ofl.

When the parts A A are turned out, position shown by dotted lines Fig. 2, the bead B will lie on thersurfaoe of the plaster and may run ,horizontally and serve as a line marking oil a dado. 7

In the modification, B is formed with a longitudinal crease B which forms a guide for the laying of a ground coat E (F1 3) of uniform thickness upon which a finis ing or second coat e may be laid, the plasterer working from the part of the head which is outside of said crease in determining the thickness of the finishing coat.

It is noted that the form of and B is such that they can be very cheaply manufactured and applied as well to any angle of corner as to a level surface, that the outer margins of the parts'A A are adapted to be nailed either to' a wooden or a brick wall surface and that the opposite or inner mar 'ns (1 are adapted to engage the part B or 1 through the slot 1; or b so that the inner margins will be held t%ether and secure the said parts A A and or B in the several working relations shown and described.

I am aware that metal beads for lastering have been made with a strip of s eet metal so shaped as'to' present at its mid-width a tube or channel from said channel having their outer edges inturnedand forming auxiliary flanges resulting in the production of a triangular space along said channel to receive the head of a clip attached the bead to a 001- similar form in which the flanges or walls diverging from the channel were outtum I therefore do not 'claim such a combination broadly; but

I claim:
